FM Transmitter and FM Radio Transmitters, 3 Volt FM Transmitter Reviews:

  • --> This kit has not worked for me even though the instructions were simple and I had great hopes. I sent the kitI assembled to the manufacturer (Hong Kong) to figure out the problem. He could not, so he sent me another one that he assembled, but that one either did not work. If you want to try, it may be at your own risk.

  • --> Dont know the problem youve got, but I made up my own board and it works a treat, use earphones on receiver
